This Standard covers the emission of voltage changes, voltage fluctuations and flicker produced by equipment and impressed on the public low-voltage supply system. It specifies the limits of voltage changes produced by equipment tested under specified conditions. It is primarily applicable to electrical and electronic equipment having a rated input current from 16 A up to and including 75 A.
